Siemens Q115DFWG - 15A, AFCI Arc-Fault Circuit Breaker

The Siemens Q115DFWG 15A AFCI Arc-Fault Circuit Breaker is a precise, reliable protection solution for demanding electrical environments. Engineered to provide dependable overcurrent protection with advanced arc-fault detection, this unit helps safeguard distribution panels and motor control centers in industrial, commercial, and OEM settings.

Why choose the Q115DFWG

• AFCI protection detects dangerous arcing and interrupts power to reduce fire risk, helping keep critical equipment and facilities safer.
• 15A current rating makes it suitable for a wide range of branch circuits across panelboards, switchboards, control panels, and OEM equipment.
• Versatile compatibility designed for easy integration into distribution panels and motor control centers, supporting streamlined installation in both new builds and retrofit projects.
• Industrial, commercial, and OEM readiness ideal for applications where dependable protection and safe operation are paramount, from manufacturing lines to complex control systems.

Where it shines (use cases)

In industrial environments, the Q115DFWG protects feeders feeding motors, drives, and control circuits within panelboards and motor control centers. In commercial settings, it helps secure lighting, power distribution, and equipment circuits against arc faults. For OEM equipment, it provides integrated, robust protection right at the source, supporting safer, codes-compliant operation of compact control panels and integrated systems.

How it protects your system

Arcs — often invisible and destructive — are detected by the AFCI mechanism, which rapidly interrupts the circuit when irregular arcing is sensed. This targeted response minimizes potential insulation damage and reduces the likelihood of arc-related fires, while preserving normal operation on non-faulty circuits.
